Tor relay on a rpi2

This is a little walkthrough on using ansible to setup a tor relay (not an exit node)
on a Raspberry Pi. It might be overhead to
use ansible for this purpose but the initial goal was to experiment with ansible.

First go to Raspberry Pi download
and download the raspbian iso. Then flash it to your SD card and start your Raspberry Pi.
A comprehensive guide is available here.
You might also want to follow the config setup doc here
which explains the different options of the raspi-config tool.

Once you have your Raspberry Pi up and running, let's setup ansible
to install and set up a tor relay.
